The file 'Wooly Sheep Duplo 3D Printer Model' is (stl) file type, size is 3.4MB.
I took the wooly sheep from http://www.thingiverse.com/thing:95721 and I add 3 pieces of duplo, generated with openscad and doplo factory script (http://www.thingiverse.com/thing:2106). I made the union of all the shapes with blender.
